I hope this information clears everything up. Please let me know if you have any further questions. <br /> Thank you, <br /> Sam Ly <br /> On Wed, May 27, 2026 at 7:56 AM Sammons, Lynsey[EHD] <lsammons(a)sjgov.org>wrote: <br /> Thanks for the update, Sam—is the colorant waste the same as the toner waste?We're specifically <br /> interested in the toner waste, since that is the waste stream noted in the violation for failure to make <br /> a hazardous waste determination. <br /> I'm still not clear about whether you are managing the toner waste as hazardous waste. Do the <br /> containers meet the California definition of empty when they become waste? Does any <br /> pourable/scoopable amount of toner ever remain in the containers? How are you storing them at the <br /> facility? I see that Clean Harbors did a pickup, but I can't tell what formulations they are—do they <br /> match the SDSs you provided?Or are those other waste streams?That needs to be documented. <br /> For the 96-2000 PPG Formula Pro Colorant Concentrate BX Lamp Black—SDSs are only one option <br /> for making a hazardous waste determination. You can also use analytical results from lab testing, <br /> generator knowledge, or if you have another method in mind, we can talk about it. It's the facility's <br /> responsibility, as the generator of the waste, to make the full hazardous waste determination. You <br /> can also opt just to manage it as hazardous waste. <br /> Let me know what questions you have. <br /> Lynsey Sammons <br /> Registered Environmental Health Specialist <br /> Cell: (209) 616-3067 <br /> Office: (209)468-3420 <br /> San Joaquin County Environmental Health Department <br /> 1868 E.Hazelton Avenue,Stockton,CA.95205 <br /> 8 <br />
